Description

Technical Field

[0001] This utility model relates to the field of motorcycle technology, and in particular to a battery pack and electric motorcycle that prevents battery movement. Background Technology

[0002] Chinese Patent No. CN219565343U discloses a battery clamping device for an electric motorcycle. The device includes a motor housing, in which a rotating pressure plate for clamping the battery is rotatably mounted. A sleeve is fixedly mounted on the rotating pressure plate parallel to its own rotation axis. A movable rod is provided on the rotating pressure plate. A pair of limiting inner rods are movably mounted inside the sleeve. A pair of connecting rods are hinged to the ends of the movable rods and respectively hinged to the limiting inner rods. Springs are sleeved on the movable rods to drive the limiting inner rods to extend from both ends of the sleeve. When the rotating pressure plate clamps the battery, the limiting inner rods extend and insert into holes on the inner wall of the frame to prevent the rotating pressure plate from disengaging from the clamping position.

[0003] The aforementioned battery clamping device must include a connecting rod, a movable rod, and a structure on the rotating pressure plate to guide the movable rod in order to enable the operating limit rod to extend or retract. This makes the battery clamping device relatively complex, increasing the difficulty of production and assembly, and resulting in higher production costs. Utility Model Content

[0004] To address the shortcomings of existing battery clamping devices, which are complex in structure, leading to difficulties in production and assembly and high production costs, the primary objective of this invention is to provide a battery pack that can prevent battery movement. The clamping device of this battery pack has a simpler structure and is easier to operate.

[0005] To solve the above-mentioned technical problems, the present invention provides a solution through the following technical method:

[0006] A battery pack for preventing battery movement includes a battery box mounted on a vehicle frame, a battery, a rotating assembly for pressing the battery by flipping relative to the battery box, and a locking assembly for locking the rotating assembly relative to the battery box when the rotating assembly presses down on the battery. The locking assembly includes a telescopic rod that is telescopically mounted relative to the rotating assembly and is inserted into and limited by the battery box or vehicle frame after partially extending out, and an operating member protruding from the outer wall of the telescopic rod for driving the telescopic rod to move.

[0007] Using the above solution, the movement of the telescopic rod is controlled by the operating component protruding from its outer wall. When it is necessary to unlock the rotating assembly, the operator only needs to manually move the operating component to disengage the telescopic rod from the vehicle frame, and then flip the rotating assembly to disengage it from the battery box. Compared with the prior art, this structure omits the structures on the movable rod, connecting rod, and rotating assembly used to restrict the guidance of the movable rod. Only one operating component needs to be set on the telescopic rod. The connection method between the operating component and the telescopic rod includes, but is not limited to, welding, interference fit, bolt connection, etc. Therefore, the mechanism for pressing the battery in this solution is easy to manufacture and assemble, and has a lower cost.

[0008] Preferably, the telescopic rod guide telescopic arrangement is located inside a sleeve fixedly mounted on a rotating assembly, and the sleeve has a stroke groove for the operating component to pass through and to limit the range of motion of the operating component.

[0009] Using the above solution, the travel groove can limit the maximum extension length of the telescopic rod, preventing it from detaching from the sleeve.

[0010] Preferably, an elastic element is provided inside the sleeve at the end of the telescopic rod away from its extended end, which drives the telescopic rod to be in a partially extended state under normal conditions.

[0011] The purpose of the elastic element in the above scheme is twofold: first, to prevent the telescopic rod from disengaging from the frame; and second, to enable the telescopic rod to extend automatically. When the telescopic rod is aligned with the limiting groove on the frame, it can automatically pop out and extend into the limiting groove, eliminating the need to manually push the telescopic rod into the limiting groove.

[0012] Preferably, the sleeve is located at the end of the rotating frame away from its own rotation center and parallel to the rotation axis of the rotating frame. Two sets of telescopic rods are provided and inserted into both ends of the sleeve. Two sets of operating parts are provided and located at opposite ends of the two telescopic rods respectively. The two operating parts have the same protruding direction. The elastic element is located between the two telescopic rods and its two ends are elastically abutting against the two telescopic rods respectively.

[0013] Using the above solution, this solution is the preferred solution for the telescopic rod setting method. The telescopic rod can extend from both ends and cooperate with the limiting groove on the frame, thereby increasing the locking firmness.

[0014] Preferably, two stroke grooves are provided at intervals on the sleeve, and the two operating parts are located in independent stroke grooves.

[0015] Using the above solution, users only need to pinch the two operating parts together to retract the telescopic rod. However, when the two operating parts share a single travel groove, during the pinching process, neither operating part is in contact with the ends of its respective travel groove. If the operator's hand shifts to one side, the telescopic rod will slide along the sleeve, potentially causing one of the telescopic rods to extend out of the sleeve and re-insert into the limiting groove, preventing the rotating component from unlocking properly. In this solution, each operating part corresponds to a travel groove. When one operating part is moved to contact the inner end of the two travel grooves, a point of force is formed. At this point, continuing to pinch the operating part will drive the other operating part closer to it, avoiding the phenomenon that the rotating component cannot unlock smoothly due to the operator's hand shifting when pinching the operating part.

[0016] Preferably, the operating element protrudes from the side of the sleeve facing away from the rotating assembly.

[0017] In this scheme, the purpose of placing the sleeve at this location is to save effort. The entire rotating component can be considered as a lever arm, with the end farther from the rotation center requiring less force to flip the rotating component. The purpose of limiting the direction of the protruding operating parts is to make the operation process smoother. Specifically, the operator only needs to use the web of their hand to hold the two operating parts, then bend their thumb and forefinger to prevent the operating parts from detaching from the web of their hand, and then apply force to pinch the operating parts together. At the same time, the operator can also use the other fingers to hold the sleeve or rotating component, and drive the rotating component to flip by pushing and pulling. Pinching the operating parts with the web of the hand is less strenuous than using the fingers, and can be done together with the pushing and pulling actions of the hand, making the overall operation smoother.

[0018] Preferably, the rotating assembly includes a rotating frame rotatably mounted on the battery box and a pressing component mounted on the rotating frame for pressing against the battery when the flipping component moves to near the battery box's loading / unloading port.

[0019] Preferably, the pressing component is movably mounted on the rotating frame and is self-locking. When the flipping component mates with the battery mounting position, the pressing component presses the battery twice by adjustment.

[0020] Using the above solution, if there is still a gap between the pressing component and the battery after the rotating frame is limited, the pressing component can be adjusted to press the battery tightly.

[0021] Preferably, the pressing component includes a screw rod passing through a rotating frame, an abutment end fixedly disposed at one end of the screw rod for pressing the battery, and a handle fixedly disposed at the other end of the screw rod. A nut that is screwed into the screw rod is fixedly disposed on the rotating frame. When the screw rod rotates relative to the nut, it drives the abutment end to move closer to or away from the battery box.

[0022] By adopting the above scheme, the structure of the pressing component is further defined. The cooperation between the screw and the nut enables the pressing component to eliminate tiny gaps and press the battery tightly. The pressing force depends on the degree of screw tightening.

[0023] The second objective of this utility model is to disclose an electric motorcycle, including a frame, on which a battery pack is provided to prevent battery movement as described in any of the above-mentioned solutions, the battery box is integrally formed with the frame, the frame is provided with a mounting seat for hinged connection of the rotating component, and a limiting groove is provided on the frame near the battery box access port to cooperate with the locking component.

[0024] Using the above solution, the motorcycle experiences significant bumps during operation. However, the battery pack in this solution effectively reduces wear at the connection points between the battery box and the battery caused by vibrations of the battery pack relative to the battery box, thus improving the safety of the electric motorcycle.

[0025] This utility model, by adopting the above technical solution, has significant technical effects: the movement of the telescopic rod in this solution is controlled by the operating component protruding on its outer wall. When it is necessary to unlock the rotating component, the operator only needs to manually move the operating component to disengage the telescopic rod from the vehicle frame, and then flip the rotating component to disengage it from the battery box. Compared with the prior art, this structure omits the features of the movable rod, connecting rod, and limiting the guiding movement of the movable rod on the rotating component. Only one operating component needs to be set on the telescopic rod. The connection method between the operating component and the telescopic rod includes but is not limited to welding, interference fit, bolt connection, etc. Therefore, the mechanism for pressing the battery in this solution is easy to produce and assemble, and the cost is low.

[0036] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0037] Example 1

[0038] An electric motorcycle, according to Figure 1 , 2 As shown, the vehicle includes a frame 1, on which a seat 102 is mounted. Below the seat 102 is a battery pack designed to prevent battery movement. The battery pack includes a battery box 101 integrally formed on the frame 1. A battery (not shown in the figure) is disposed inside the battery box 101. The top of the battery box 101 has an opening for inserting or removing the battery. A mounting base 10 is fixedly mounted on the frame 1, and a rotating frame 2 is hinged to the mounting base 10. The above is prior art and will not be described in detail in this embodiment.

[0039] The rotating frame 2 is equipped with a locking component. When the rotating frame 2 is flipped to a position close to the battery compartment 101 access port, the locking component cooperates with the frame 1 to restrict the flipping action of the rotating frame 2. Figure 3 , 5 As shown in Figure 6, the locking assembly includes a sleeve 5 fixedly disposed at the end of the rotating frame 2 away from the mounting base 10. The sleeve 5 is parallel to the axis of rotation of the rotating frame 2. A set of telescopic rods 6 are telescopically disposed at both ends of the sleeve 5. An operating member 7 is fixedly connected to the opposite ends of the two telescopic rods 6. A stroke groove 51 is provided on the sleeve 5 for the operating member 7 to pass through and move synchronously with the telescopic rods 6. The stroke groove 51 can limit the range of motion of the operating member 7. In this embodiment, the sleeve 5 passes through the rotating frame 2, and the contact parts of the two are welded and fixed. The operating member 7 and the telescopic rod 6 are interference fit, and the two operating members 7 protrude in the same direction. Figure 3 , 5As shown, the sleeve 5 is provided with an elastic element 8 that drives the telescopic rod 6 to extend partially from the sleeve 5. In this embodiment, the elastic element 8 includes a spring disposed between the two telescopic rods 6, and the two ends of the spring elastically abut against the two telescopic rods respectively.

[0040] The rotating frame 2 is movably equipped with a self-locking pressing component 3, according to... Figure 6 , 7 As shown in Figure 8, the pressing component 3 includes a screw 301 that passes through the rotating frame 2. A nut 9 for screwing the screw 301 is welded and fixed on the rotating frame 2. One end of the screw 301 is fixedly provided with an abutment end 302 for pressing the battery. The other end of the screw 301 is fixedly provided with a handle 303. When the screw 301 rotates relative to the nut 9, it drives the abutment end 302 to move closer to or away from the battery box 101.

[0041] Based on the above structure, refer to Figures 1-8 It can be seen that the electric motorcycle in this embodiment is equipped with a battery pack that prevents battery movement. Compared with existing battery packs, this battery pack omits the features of movable rods, connecting rods, and limiting the movement of movable rods on rotating components. It only has an operating member 7 protruding on each telescopic rod 6. The operating member 7 only needs to be inserted into the telescopic rod 6 with an interference fit. Its assembly and production difficulty is low, and the required cost is low. Moreover, during operation, people only need to use one hand to pinch the two operating members 7 together in the middle to drive the telescopic rod 6 to retract, which will drive the telescopic rod 6 to retract into the sleeve 5. After releasing the operating member 7, the telescopic rod 6 will automatically pop out under the action of the elastic member 8.

[0042] Example 2

[0043] Based on Example 1, this example further defines an electric motorcycle, according to... Figure 9 As shown, the sleeve 5 is located at the end of the rotating frame 2 away from the mounting base 10, and the operating component 7 protrudes from the side of the sleeve 5 facing away from the rotating assembly.

[0044] In this embodiment, the purpose of placing the sleeve 5 at this location is to save effort. The entire rotating assembly can be regarded as a lever arm, and the end farther from the rotation center requires less force when flipping the rotating assembly. The purpose of limiting the protruding direction of the operating member 7 is to make the operation process smoother. Specifically, the operator only needs to use the web of their hand to hold the two operating members 7, then bend their thumb and forefinger to prevent the operating members 7 from detaching from the web of their hand, and then apply force to pinch the operating members 7 together. At the same time, the operator can also use the other fingers to hold the sleeve 5 or the rotating assembly, and drive the rotating assembly to flip by pushing and pulling. Pinching the operating members 7 with the web of the hand is less strenuous than using the fingers, and can be done together with the pushing and pulling actions of the hand, making the overall operation smoother.

[0045] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
